Description

Technical Field

[0001] This utility model relates to the field of pipe pile end cap processing technology, and in particular to an automatic pressing machine for processing pipe pile end caps. Background Technology

[0002] Concrete pipe piles are widely used in railway systems and are gradually expanding to industrial and civil buildings, municipal works, metallurgy, ports, highways and other fields. Concrete pipe piles are mainly composed of pile body, end plate and end cap.

[0003] In the prior art, Chinese Patent Publication No. CN209681557U discloses an automatic pressing machine for prestressed pipe pile end caps, belonging to the technical field of pipe pile end cap production equipment. The key technical point of this machine is an automatic pressing machine for prestressed pipe pile end caps, including a frame. An active pressing plate is rotatably connected to the frame, and a driving component that drives the active pressing plate to rotate is fixedly connected to the frame. A driven pressing plate, parallel to the active pressing plate, is positioned directly opposite the active pressing plate. A pressing cylinder is positioned on the side of the driven pressing plate away from the active pressing plate. The piston rod of the pressing cylinder is horizontally oriented towards the driven pressing plate and rotatably connected to it. A pressing assembly is positioned above the active pressing plate, including a pressing cylinder and a pressing wheel. The piston rod of the pressing cylinder is vertically downward, and the pressing wheel is rotatably connected to the end of the piston rod of the pressing cylinder. The rotation axis of the pressing wheel is parallel to the rotation axis of the rotating pressing plate. When the sealing plate abuts against the active pressing plate, the pressing wheel is positioned directly above the groove, thereby improving the production efficiency of the end caps.

[0004] However, in actual use, the processed end caps roll down the inclined unloading platform under their own weight. Since the end caps themselves have a certain weight and there is no cushioning during the fall, frequent collisions can easily cause structural deformation or surface damage, affecting product quality. The end caps roll and collide directly on the unloading platform, which not only generates a lot of noise, but may also cause scratches on the surface of the end caps and wear on the structure of the unloading platform. Long-term use requires frequent maintenance, so improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic pressing machine for processing pipe pile end caps, which avoids problems such as easy deformation, high noise, and unstable guidance during end cap feeding, and significantly improves the processing quality of end caps.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic pressing machine for processing pipe pile end caps, comprising a pressing machine body, a feeding platform fixedly connected to the inner wall of the pressing machine body, a discharge trough fixedly connected to one end of the feeding platform, a guide roller rotatably connected to the inner wall of the discharge trough, a rubber layer fixedly connected to the outer surface of the guide roller, a support rod fixedly connected to one end of the discharge trough, a sleeve slidably connected to the outer surface of the support rod, an arc-shaped frame fixedly connected to the top of the sleeve, shock-absorbing cotton fixedly connected to the top of the arc-shaped frame, a pipe pile end cap provided on the top of the shock-absorbing cotton, and elastic clips fixedly connected to both sides of the arc-shaped frame.

[0007] By adopting the above technical solution, after the pipe pile end cap is processed by the pressing machine body, it naturally falls onto the inclined unloading platform. The surface of the unloading platform can be covered with damping material to provide initial cushioning for the falling end cap, effectively avoiding deformation and noise caused by the initial impact. Subsequently, under the action of gravity, the pipe pile end cap rolls along the unloading platform into the discharge chute. The soft rubber layer contacts the surface of the end cap, providing secondary cushioning protection to prevent surface scratches and significantly reducing the noise generated when the end cap rolls. The rotation design of the guide roller greatly reduces frictional resistance, ensuring smooth movement of the end cap. The end cap finally moves to the end of the discharge chute. As the end cap rolls out along the guide roller, its inertia causes it to slightly rise to the top of the arc frame. The shock-absorbing cotton on the top of the arc frame reduces the final impact and vibration when the end cap stops. At the same time, a pair of elastic clamps fixed on both sides of the arc frame undergo elastic deformation under the slight impact force of the end cap, and use their restoring force to gently and reliably clamp the two sides of the pipe pile end cap, ensuring that the end cap stays stably and neatly in the predetermined position, which is convenient for subsequent removal of the end cap. The multi-stage progressive buffering and guiding avoids problems such as easy deformation, high noise, and unstable guidance when the end cap is unloaded, and significantly improves the processing quality of the end cap.

[0008] A further feature of this invention is that a rubber protrusion is fixedly connected to the outer surface of the elastic clip, and an anti-slip particle layer is fixedly connected to the outer surface of the rubber protrusion.

[0009] By adopting the above technical solution, the rubber protrusion surface is arc-shaped, and the elastic clip does not damage the surface of the pipe pile end cap when clamping.

[0010] A further feature of this invention is that the outer surface of the rubber layer is coated with a wear-resistant coating, and rubber particles are provided on the top of the feeding platform.

[0011] By adopting the above technical solution, the wear-resistant coating increases the wear resistance of the rubber layer, and the rubber particles serve as the damping material of the feeding platform.

[0012] A further feature of this invention is that a support platform is fixedly connected to the bottom of the discharge trough, and one end of the support platform has a clearance cavity.

[0013] By adopting the above technical solution, the support platform supports the discharge chute, making it correspond to the unloading platform.

[0014] A further feature of this invention is that a cylinder is fixedly connected to the top of the inner wall of the clearance cavity, and a telescopic rod is fixedly connected to the output end of the cylinder.

[0015] By adopting the above technical solution, the cylinder is activated during material discharge, driving the telescopic rod to extend upward.

[0016] A further feature of this invention is that a bracket is fixedly connected to the top of the telescopic rod, and a positioning block is fixedly connected to the top of the bracket.

[0017] By adopting the above technical solution, the bracket is lifted upward, causing the positioning block to move upward.

[0018] A further feature of this invention is that a positioning groove is provided at the bottom of the arc-shaped frame, and the inner wall of the positioning groove is inserted into the positioning block.

[0019] By adopting the above technical solution, the positioning block is inserted into the positioning slot, which facilitates the lifting of the arc-shaped frame.

[0020] A further feature of this invention is that a retaining sleeve is fixedly connected to the bottom of the arc-shaped frame, and a support rod is fixedly connected to the bottom of the inner wall of the discharge trough.

[0021] By adopting the above technical solution, the ferrule separates from the support rod, and the arc-shaped frame rises, making it easier to remove the end cap.

[0022] A further feature of this invention is that the number of support poles is four, and the four support poles are divided into two groups of two, with a height difference between each group of support poles.

[0023] By adopting the above technical solution, the height difference between the two sets of support poles corresponds to the bottom of the arc-shaped frame, resulting in a high support effect.

[0024] A further feature of this invention is that the number of the guide rollers is several, and the several guide rollers are arranged in an inclined array.

[0025] By adopting the above technical solution, the guide rollers are distributed at equal intervals and inclined, thus avoiding jamming during material feeding.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the coordinated arrangement of the pressing machine body, unloading platform, discharge chute, guide roller, rubber layer, support rod, sleeve, arc frame, shock-absorbing cotton, pipe pile end cap, and elastic clamp, enables the device to achieve the following during use: The surface of the unloading platform can be covered with damping material to initially buffer the falling end cap, effectively preventing deformation and noise caused by the initial impact. Subsequently, under the action of gravity, the pipe pile end cap rolls along the unloading platform into the discharge chute. The soft rubber layer contacts the end cap surface, providing secondary buffer protection and preventing surface scratches. This significantly reduces the noise generated during the rolling of the end cap. The rotation design of the guide roller greatly reduces frictional resistance, ensuring… The end cap was moved smoothly to the end of the discharge chute. As the end cap rolled out along the guide roller, its inertia caused it to slightly rise to the top of the arc frame. The shock-absorbing cotton on the top of the arc frame reduced the final impact and vibration when the end cap stopped. At the same time, a pair of elastic clips fixed on both sides of the arc frame underwent elastic deformation under the slight impact of the end cap, and used their restoring force to gently and reliably hold the two sides of the pipe pile end cap, ensuring that the end cap was stably and neatly stopped in the predetermined position, which facilitated the subsequent removal of the end cap. The multi-stage progressive buffer and guidance avoided problems such as easy deformation, high noise, and unstable guidance when the end cap was unloaded, and significantly improved the processing quality of the end cap.

[0028] 2. This utility model, through the coordinated arrangement of rubber protrusions, wear-resistant coating, rubber granules, support platform, clearance cavity, cylinder, telescopic rod, bracket, positioning block, positioning groove, ferrule, and frame rod, enables the device to achieve the following when in use: the surface of the rubber protrusions is arc-shaped, the elastic clamp does not damage the surface of the pipe pile end cap when clamped, the wear-resistant coating increases the wear resistance of the rubber layer, the cylinder is activated when discharging, driving the telescopic rod to extend upward, the bracket to lift upward, and the positioning block to move upward, the positioning block inserts into the positioning groove, facilitating the lifting of the arc-shaped frame, the ferrule separates from the frame rod, the arc-shaped frame rises, facilitating the removal of the end cap.

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] An automatic pressing machine for processing pipe pile end caps includes the following embodiments:

[0037] Example 1:

[0038] Reference Figure 1-4 The inner wall of the pressing machine body 1 is fixedly connected to the feeding platform 2. One end of the feeding platform 2 is fixedly connected to the discharge trough 3. The inner wall of the discharge trough 3 is rotatably connected to the guide roller 4. The outer surface of the guide roller 4 is fixedly connected to the rubber layer 5. One end of the discharge trough 3 is fixedly connected to the support rod 6. The outer surface of the support rod 6 is slidably connected to the sleeve 7. The top of the sleeve 7 is fixedly connected to the arc frame 8. The top of the arc frame 8 is fixedly connected to the shock-absorbing cotton 9. The top of the shock-absorbing cotton 9 is provided with the pipe pile end cap 10. Both sides of the arc frame 8 are fixedly connected to the elastic clips 11.

[0039] Specifically, after the pipe pile end cap 10 is processed by the pressing machine body 1, it falls naturally onto the inclined unloading platform 2. The surface of the unloading platform 2 can be covered with damping material to provide initial cushioning for the falling end cap, effectively avoiding deformation and noise caused by the initial impact. Subsequently, under the action of gravity, the pipe pile end cap 10 rolls along the unloading platform 2 into the discharge chute 3. The soft rubber layer 5 contacts the surface of the end cap, providing secondary cushioning protection to prevent surface scratches and significantly reducing the noise generated when the end cap rolls. The rotation design of the guide roller 4 greatly reduces frictional resistance, ensuring smooth movement of the end cap. Finally, the end cap moves to the end of the discharge chute 3. As the end cap rolls out along the guide roller 4, its inertia causes it to slightly rise to the top of the arc frame 8. The shock-absorbing cotton 9 on the top of the arc frame 8 reduces the final impact and vibration when the end cap stops. At the same time, a pair of elastic clips 11 fixed on both sides of the arc frame 8 undergo elastic deformation under the slight impact force of the end cap, and use their restoring force to gently and reliably clamp the two sides of the pipe pile end cap 10, ensuring that the end cap stays stably and neatly in the predetermined position, which is convenient for subsequent removal of the end cap. The multi-level progressive buffer and guide avoids problems such as easy deformation, high noise, and unstable guidance when the end cap is unloaded, and significantly improves the processing quality of the end cap.

[0040] Example 2:

[0041] Reference Figure 1-4 The outer surface of the elastic clip 11 is fixedly connected to a rubber protrusion 12, and the outer surface of the rubber protrusion 12 is fixedly connected to an anti-slip granular layer. The outer surface of the rubber layer 5 is coated with a wear-resistant coating 13. Rubber granules 14 are provided on the top of the feeding platform 2. A support platform 15 is fixedly connected to the bottom of the discharge chute 3. One end of the support platform 15 has a clearance cavity 16. A cylinder 17 is fixedly connected to the top of the inner wall of the clearance cavity 16. A telescopic rod 18 is fixedly connected to the output end of the cylinder 17. The top of the telescopic rod 18 is fixedly connected to... A bracket 19 is attached, and a positioning block 20 is fixedly connected to the top of the bracket 19. A positioning groove 21 is opened at the bottom of the arc frame 8. The inner wall of the positioning groove 21 is inserted into the positioning block 20. A sleeve 22 is fixedly connected to the bottom of the arc frame 8. A support rod 23 is fixedly connected to the bottom of the inner wall of the discharge chute 3. There are four support rods 23. The four support rods 23 are divided into two groups. There is a height difference between each group of support rods 23. There are several guide rollers 4. The several guide rollers 4 are arranged in an inclined array.

[0042] Specifically, the surface of the rubber protrusion 12 is arc-shaped, the elastic clamp 11 does not damage the surface of the pipe pile end cap 10 when clamping, the wear-resistant coating 13 increases the wear resistance of the rubber layer 5, the rubber granules 14 serve as the damping material of the unloading platform 2, the support platform 15 supports the discharge chute 3 so that it corresponds to the unloading platform 2, the cylinder 17 is activated when discharging, driving the telescopic rod 18 to extend upward, the bracket 19 is lifted upward, driving the positioning block 20 to move upward, the positioning block 20 is inserted into the positioning groove 21, which facilitates the lifting of the arc frame 8, the clamp 22 separates from the frame rod 23, the arc frame 8 rises, which facilitates the removal of the end cap, the height difference between the two sets of frame rods 23 corresponds to the bottom of the arc frame 8, and the support effect is high, the guide rollers 4 are evenly inclined to avoid jamming when guiding materials.

[0043] In this invention, the surface of the unloading platform 2 can be covered with damping material to provide initial cushioning for the falling end cap, effectively avoiding deformation and noise caused by the initial impact. Subsequently, the pipe pile end cap 10 rolls into the discharge chute 3 along the unloading platform 2 under the action of gravity. The soft rubber layer 5 contacts the surface of the end cap, providing secondary cushioning protection to prevent surface scratches and significantly reducing the noise generated when the end cap rolls. The rotation design of the guide roller 4 greatly reduces frictional resistance, ensuring smooth movement of the end cap. The end cap finally moves to the end of the discharge chute 3. When the end cap rolls out along the guide roller 4, its inertia causes it to slightly impact the top of the arc frame 8. The shock-absorbing cotton 9 on the top of the arc frame 8 reduces the final impact and vibration when the end cap stops. At the same time, a pair of elastic clips 11 fixed on both sides of the arc frame 8 cushion the slight impact of the end cap. Under impact, the end cap 10 undergoes elastic deformation and uses its restoring force to gently and reliably clamp both sides of the pipe pile end cap 10, ensuring that the end cap remains stably and neatly in the predetermined position, facilitating subsequent removal of the end cap. The multi-stage progressive buffer and guide avoid problems such as easy deformation, high noise, and unstable guidance during end cap unloading, significantly improving the processing quality of the end cap. The surface of the rubber protrusion 12 is arc-shaped, and the elastic clamp 11 does not damage the surface of the pipe pile end cap 10 when clamping. The wear-resistant coating 13 increases the wear resistance of the rubber layer 5. When unloading, the cylinder 17 is activated, driving the telescopic rod 18 to extend upward, the bracket 19 to lift upward, and the positioning block 20 to move upward. The positioning block 20 is inserted into the positioning groove 21, which facilitates the lifting of the arc-shaped frame 8. The ferrule 22 separates from the frame rod 23, and the arc-shaped frame 8 rises, making it easy to remove the end cap.
